Hiding and displaying panels


Often in web applications, there is a need to dynamically display or hide objects based on certain events triggered by the web user. One such example is a dynamic navigation bar where a sub navigation is to be turned on/off. In this recipe, we will see how to achieve this using jQuery.

Getting ready

  1. Add a new web form Recipe7.aspx to the current project.

  2. Create a couple of main menu and sub-menu items in a vertical navigation bar using ASP.NET panel controls as shown in the following example:

    <asp:Panel class="content_head" runat="server">Menu Item 1</asp:Panel>
    <asp:Panel class="content_body" runat="server">Sub Menu Item 11
    <br />Sub Menu Item 12</asp:Panel>
  3. Define the css style of the main menu item as follows:

    .content_head
        {
            width:150px;
            height:30px;
            background-color:#CCCCCC;
            cursor:pointer;
        }
  4. Define the css style of the sub-menu item as follows:

    .content_body
        {
            display:none;
      ...
